JSON Fetch Random Record

Searched everywhere for this one. Hopefully it will help someone else out...

I was looking for a way to filter a JSON dataset by an ID number. Here goes...

1. Step 1 : Create your JSON Data.
   
   
   var item = [
   { "id": "0", "language": "English"},
   { "id": "1", "language": "Spanish"},
   { "id": "2", "language": "French"},
   { "id": "3", "language": "Hungarian"}
   ];
   


2. Step 2 : Function to find Unique Value:
   
   
   I cant take credit for this one. I found this at : http://stackoverflow.com/questions/604935/how-can-i-filter-json-for-unique-key-name-value-pairs. Here it is...
   
   function getDistinct(o, attr) {
   var answer = {};
   $.each(o, function(index, record) {
   answer[index[attr]] = answer[index[attr]] || [];
   answer[index[attr]].push(record);
   });
   return answer;
   }
   


3. Step 3: Create Random Number
   
   var randNo = Math.floor(Math.random() * 4); (with 4 being the same number of records contained in the JSON Dataset).
   


4. Step 4: Return unique record items
   
   
   $(function() {
   $.each(getDistinct(markers, "id"), function(groupName, recordArray) {
   var firstRecord = recordArray[randNo];
   $('
').html(firstRecord.language).appendTo('#results');
});
});

Finally, the body simply contains an unordered list with an id of results to contain the information.

ASP.NET Routing 4.0 Handle Error

OK, so this took a lot of searching, but this worked. Not sure why it isn't put into the Web.Config file initially, or that there isn't more documentation, as this had me going nuts. Anyways, if you get a 404 error on the ASP.NET 4.0 routing feature when you deploy to IIS7.0, take a look at this. I bet it will get you going...
